Eric Milles updated GROOVY-11804:
---------------------------------
Language: groovy
> Groovy 5 doesn't handle implicit properties
> -------------------------------------------
>
> Key: GROOVY-11804
> URL: https://issues.apache.org/jira/browse/GROOVY-11804
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 5.0.2
> Reporter: Ed T
> Priority: Major
>
> The following code compiles and works find in Groovy 4 (tested with version
> 4.0.24 and 4.0.29). It no longer compiles with Groovy 5 (tested with version
> 5.0.2). All ran on JDK25.
>
> {code:java}
> interface CustomComparable<Owner extends Comparable, O> {
> Owner getOwner()
> default boolean isLessThan(O other) {
> owner < other
> }
> default boolean isLessThanOrEqualTo(O other) {
> owner <= other
> }
> default boolean isEqualTo(O other) {
> owner == other
> }
> default boolean isGreaterThan(O other) {
> owner > other
> }
> default boolean isGreaterThanOrEqualTo(O other) {
> owner >= other
> }
> default isBetween(O left, O right) {
> owner >= left && owner <= right
> }
> }
> class MyString implements Comparable<Object>, CustomComparable<MyString,
> String> {
> private String str
>
> MyString(String str) {
> this.str = str
> }
>
> MyString getOwner() {
> return this
> }
> @Override
> int compareTo(Object o) {
> String ostr
> if (o instanceof MyString) {
> ostr = ((MyString) o).str
> } else if (o instanceof String) {
> ostr = (String) o
> } else {
> throw new UnsupportedOperationException("can't compare with object
> of class: ${o.class}")
> }
> return str.compareTo(ostr)
> }
> }
> s = new MyString("abc")
> println s.isEqualTo("abc")
> {code}
>
> When run, Groovy 5 compiler complains the following.
> {code:java}
> groovy.lang.MissingPropertyException: No such property: owner for class:
> MyString at CustomComparable.isEqualTo(ConsoleScript0:14) at
> ConsoleScript0.run(ConsoleScript0:60) {code}
> Groovy 4.x works just fine.
